Abstract

PROBLEM TO BE SOLVED: To print a picture pattern on the surface of an article such as ceramics and metal plates, at a low temperature while presenting a grave impression by forming a water-soluble glue layer on one surface of a mount having water absorbency, forming a picture pattern on the water-soluble glue layer, and covering the picture pattern with a mixture of a coating agent for light-transmissible transfer, and an adhesive for light-transmissible transfer. SOLUTION: A water-soluble glue layer 2 is formed on a mount 1 having water absorbency, and a picture pattern 3 is formed on the water-soluble glue layer 2, and further on the top of the picture pattern 3, a mixture 4 of a coating agent for light- transmissible transfer and an adhesive for light-transmissible transfer, is formed. As the coating agent for light-transmissible transfer, a film solution for printing made of an acrylic resin is preferable, and as the adhesive for light-transmissible transfer, a urea-melamine derivative is preferable. In a transfer paper which is manufactured in such a manner, the water-soluble glue layer 2 melts when dipped in water, and the mount 1 is separated, and on the surface of a base which is an article to be transferred, the mixture 4 of the picture pattern 3 are affixed with the residual glue, and the adhesive in the mixture 4 melts when being heated, and the picture pattern 3 and the coating agent are printed to the base when the adhesive is hardened.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to ceramics, glass,
150 ° C with pictures (including letters, symbols, etc.) on the surface of various articles such as ceramic products such as enamel, metal plate, colored tin etc.
The present invention relates to a low-temperature baking transfer paper used for baking at a moderate temperature.

[0002]

2. Description of the Related Art Conventionally, as such a low-temperature baked transfer paper, one described in Japanese Patent Publication No. 54-30325 is known.

[0003]

However, in the low-temperature baking transfer paper, a first film made of a thermosetting synthetic resin is formed on a water-soluble glue layer formed on a backing paper, and a picture is formed thereon. It is printed, and a second film made of a thermosetting synthetic resin is formed thereon, and a lacquer film is further formed thereon. The number of printing times is large, and a drying step is required after each printing step. Therefore, it takes a long time to manufacture and the cost increases.

Further, since the transferred picture is covered with a lacquer film, it is suitable for providing a mirror-like surface to give a photographic-like gloss. Is inappropriate for expressing.

Means for Solving the Problems, Functions and Effects As a means for solving such problems, the invention of claim 1 is to form a water-soluble glue layer on one surface of a water-absorbing backing paper,
A pattern is formed on the water-soluble glue layer, and the pattern is coated with a mixture of a translucent transfer coating agent and a translucent transfer adhesive, wherein the water-soluble glue layer, the pattern and the mixture When printing is performed, the printing is completed three times, and can be manufactured in a short time, thereby reducing the cost. In addition, the mixture of the translucent transfer coating agent and the translucent transfer adhesive is dried. Then, because it is hard to be mirror surface, the reflection of the transferred pattern is small,
It becomes a mat-like shape with ceramic glaze, expressing a solid feeling.

According to a second aspect of the present invention, in the first aspect, the mixing weight ratio of the light-transmissive transfer coating agent and the light-transmissive transfer adhesive is 9: 1 to 3: 7. The amount of adhesive is too small and the adhesion to the counterpart due to baking does not weaken. Conversely, if the amount of adhesive is too large, the adhesion occurs at room temperature and it inadvertently adheres to the counterpart during transfer and the pattern In addition, there is no possibility that the transfer papers will not be bonded to each other when the transfer papers are stacked and become unusable.

According to a third aspect of the present invention, in the invention of the second aspect, the mixing weight ratio of the light-transmissive transfer coating agent and the light-transmissive transfer adhesive is 6: 4 to 4: 6. Is extremely small, and a more profound feeling is expressed, and since the mixing ratio of the adhesive is appropriate, the transfer operation and the handling of the transfer paper are easy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a backing sheet having water absorbency, as shown in FIG. 1, a water-soluble glue layer 2 such as dextrin is formed on the backing sheet 1, and a picture pattern is formed thereon as shown in FIG. 3 is formed, and FIG.
As shown in FIG. 5, a mixture 4 of a light-transmissive transfer coating agent and a light-transmissive transfer adhesive is formed thereon.

The water-soluble glue layer 2, picture 3 and mixture 4 are formed by screen printing.

[0010] Here, as the translucent transfer coating agent, an acrylic resin film solution for printing is preferable, and a product name: DIANAL® manufactured by Mitsubishi Rayon Co., Ltd.
A film solution is suitable, and as the translucent transfer adhesive, a urea / melamine derivative is preferable, and a product name: Screen printing ink / epoxy 1300-800 medium manufactured by Seiko Advance Co., Ltd. is preferable.

The transfer paper thus manufactured is immersed in water to dissolve the water-soluble glue layer 2 and to peel off the backing paper 1, and the mixture 4 and the picture 3 are formed on the surface of the base material to be transferred. The adhesive in the mixture 4 is melted and heated by heating at 150 ° C. for about 30 minutes, and the pattern 4 and the coating agent are baked on the substrate.

The mixing weight ratio of the coating agent and the adhesive is 9:
1, 8: 2, 7: 3, 6: 4, 5: 5, 4:
6, 3: 7, 2: 8, and 1: 9 were prepared and tested. As shown in the graph of FIG.
5 has the lowest reflectivity and the solid feeling of the pattern 3 transferred to the substrate is high, and it is found that the reflectivity increases as the ratio of the coating agent becomes smaller or larger. .

On the other hand, if the mixing weight ratio of the coating agent to the adhesive exceeds 9: 1 of the sample, the amount of the adhesive is too small and the adhesive strength to the substrate at the time of baking is too low to be suitable for use. If the mixing weight ratio of the coating agent to the adhesive is less than 3: 7 of the sample, the amount of the adhesive is too large and the adhesive force is generated even at room temperature. Therefore, when the image is transferred to the substrate, it is inadvertently stuck to the substrate and the pattern 3 is cracked. It was found that not only did the transfer paper easily occur, but when the completed transfer papers were overlapped, the transfer papers stuck to each other and became unusable.

Then, it was found that the pattern 3 transferred from the sample of 6: 4 to the sample of 4: 6 had a sufficiently high solid feeling of the pattern 3 transferred to the substrate, and the transfer operation was easy.
